It is really difficult to understand what the problem is that you are describing because you really haven't described a problem. You also haven't explained what you are trying to do. Are you trying unsuccessfully to connect to a computer with that address? Are you trying (unsuccessfully) to connect a computer at that address to the internet? Any IP address that starts with 10 is a local IP address. (10.x.y.z = local address). There is absolutely no way to change that because it is a standard (I believe it was started with Novel).

I have the same problem. I also want to do a "Client-Server" TCP-IP communication on Embedded platform. IP of device that I know, but I don't know how to set IP for my board (I use Qt for coding).
@mSocket ->connectToHost("10.0.0.8",11100); //IP and port number of server
if(mSocket->waitForConnected(1000))
{
QMessageBox::information(this,"Server","Connected!");
}
else
{
QMessageBox::critical(this,"Error",mSocket->errorString());
}@
